1885160 Cannot Change Objective Post-Launch

You tried to change the campaign objective after the campaign has already been created. Meta permanently locks the objective at campaign creation time—this is by design, not a bug.

What causes this error?

You tried to change the campaign objective after the campaign has already been created. Meta permanently locks the objective at campaign creation time—this is by design, not a bug.

How to fix it

1. Create a new campaign: The only way to change an objective is to duplicate the campaign and select the new objective during creation.
2. Plan ahead: Carefully consider your objective before creating. ‘Sales’ campaigns optimize very differently from ‘Traffic’ or ‘Awareness’ campaigns.
3. Copy your settings: Use the ‘Duplicate’ feature in Ads Manager to clone all your targeting and creative settings into the new campaign.
